Abstract:
An air data probe 100 includes a probe head 102 defining a longitudinal axis between a forward tip 104 and aft base. The probe includes a port opening 125 in the forward tip. The probe includes a first conduit 128 in fluid communication with the port opening to guide fluid flow from the port opening to a first chamber 130, wherein the first chamber 130 is downstream from the port opening. The probe also comprises a second conduit 132, offset radially and circumferentially from the first conduit 128, in fluid communication with the first chamber 130 to guide fluid flow from the first chamber to a second chamber 134, wherein the second chamber 134 is downstream from the first chamber 130, wherein the offset between the first and second conduits is configured to prevent particle ingestion from the port opening from entering the fluid conduit.
Abstract:
An air data probe (10;26;42) includes an air data probe body (12;28;44) and an additively manufactured heater (100-900) on the air data probe body.
Abstract:
An air data probe 1 is disclosed. The air data probe 1 may include a probe body 4 having an interior cavity 10-1 and coated by a protective shell 5. A sensing port 3-1 may be disposed in the air data probe and may extend through the probe body. The sensing port 3-1 may also be lined by the protective shell 5. The protective shell 5 may be made of an austenitic nickel-chromium alloy, or stainless steel, or any relatively corrosion resistant material. The probe body 4 may be made of nickel, or a nickel alloy, or any relatively thermally conductive material. The protective shell may 5 be joined to the probe body 4 by additive manufacturing, such as laser cladding. In this manner, an air data probe capable withstanding high temperatures without corrosion and yet also being relatively thermally conductive is disclosed.
Abstract:
A probe head of an air data probe includes a unitary body (22) extending from a first end (18) to a second end (20) of the probe head and a rod heater. The body includes an inlet (28) adjacent the first end of the probe head, an air passageway (30) extending through the body from the inlet to the second end of the probe head, a water dam (32) extending radially through the body such that the air passageway is redirected around the water dam, and a heater bore (34) extending within the body. The rod heater (24) is positioned within the heater bore.
Abstract:
An additive manufacturing apparatus including an energy source (102) configured for transmitting a laser, a build plate (106) configured to have a powder (108) configured to be heated by the laser for additive manufacturing, at least one mirror (110) positioned between the energy source and the build plate, the at least one mirror configured to direct the laser from the energy source to the build plate, and an optical isolator (112) configured to reduce energy bounce back into the energy source.
Abstract:
An air data probe (46) has a pitot tube with a tap (47) at a forward end (48) that defines an inner flow path. The inner flow path decreases in the cross-sectional area until reaching a throat (50). The inner flow path has cross-sections that are generally cylindrical and also has sections of removed material (52).
Abstract:
An air data probe includes a strut including a socket defining an interior surface of the strut and an interior groove extending radially into the interior surface. The air data probe also includes a probe head partially positioned within the socket, the probe head including an exterior surface and an exterior groove extending radially into the exterior surface, the exterior groove being axially alignable with the interior groove. The air data probe further includes a retaining ring partially positionable within the exterior groove and partially positionable within the interior groove when the exterior groove and the interior groove are axially aligned to axially retain the probe head to the strut while allowing the probe head to rotate relative to the strut.
Abstract:
A corrosion resistant sleeve (28; 128) for an air data probe (10) with the sleeve (28; 128) being cylindrical in shape with a first end (20; 120) and a second end (22; 122), at least one circumferentially extending groove (32; 132) on an outside of the sleeve (28; 128) configured to accommodate coils (26; 126) of a heater, and a bore (34; 134) at a center of the sleeve (28; 128) and extending between the first end (20; 120) and the second end (22; 122) configured to provide a pneumatic pathway that allows atmospheric conditions to reach measurement equipment of the air data probe (10).
